all: comply with linter recommendations #2

HTTP request now implicitly create request with context.

Any false positive related to not closing HTTP response body has been
annotated with "nolint:bodyclose".

In the example code, use consistent "// Output:" comment format, by
prefixing with single space.
Any comment on code now also prefixing with single space.

An error returned without variables now use [errors.New] instead of
[fmt.Errorf].
Any error returned using [fmt.Errorf] now wrapped using "%w" instead of
"%s".
Also, replace error checking using [errors.Is] or [errors.As], instead
of using equal/not-equal operator.

Any statement like "x = x OP y" now replaced with "x OP= y".
Also, swap statement is simplified using "x, y = y, x".
Any switch statement with single case now replaced with if-condition.

Any call to defer on function or program that call [os.Exit], now
replaced by calling the deferred function directly.

Any if-else condition now replaced with switch statement, if possible.
